Dangers of Asbestos

What is asbestos? Asbestos is defined as “a fibrous mineral, either amphibole or chrysotile, formerly used for making incombustible or fireproof articles”, or in lay-man’s terms it is a material that is used in housing which has been deemed fireproof. While this sounds like the perfect material to use to insulate homes, it has actually been deemed as an illegal material. Of course, the government did not only on a whim declared the illegal use of asbestos, but scientific research have proven that the dangers of asbestos far outweigh the benefits in can give.

Asbestos was widely used in the early 1900s and there were not enough studies to show evidence about its hazards. Over time and with the sophistication of the tools in scientific research, asbestos is found to be potentially hazardous to human health. Along with this, there were studies and tests that have established a strong correlation between asbestos and fibrotic lung disease as well as changes in the lining of the chest cavity. Despite the dangers of asbestos to human health, it is still commonly present anywhere.  It can be found in products such as cement/plaster as well as floor and ceiling tiles and inhalation of fumes causes the most harm. The dangers of asbestos then creates an issue since houses from the 80’s are still in existence to date and most homeowners are not aware of what materials or procedures were utilized in the construction.

In situations like this, BC Green Construction & Demolition mission to contain the dangers of asbestos comes into play. We offer our affordable expertise and asbestos abatement services in Lower Mainland British Columbia. Not only do we provide help with the removal, we also take the responsibility of clean up and safe disposal of the hazardous material.

Asbestos in Your Home

Asbestos in your Home

Asbestos in your home can be found anywhere, especially if the home was built during the 19th century. Asbestos is a naturally  occurring fibrous  material that was a popular building material from the 1950s  to 1990s.   It was used extensively because it is an insulator,  has good fire  protection properties, has tensile strength, and is resistant to  chemical erosion. Unfortunately, it’s hard to  know if you’re  working with asbestos because it is often mixed with other  materials.  However, if you work in a building built before 1990, it’s likely  that  at least some parts of the building have asbestos.


Common uses

Some of the more common uses of asbestos in buildings are shown below

Spray applied fireproofing

Asbestos in your home can be found as fire protection on  structural supports (e.g. columns and beams), walls and ceilings.   Asbestos containing and non-asbestos containing forms of spray applied  fireproofing may be found.

Mechanical insulation

Mechanical insulation can be  found on mechanical systems, including: boilers, vessels, tanks and  pipes.  These materials often have a high asbestos content.


In older homes, the paper backing  on some linoleum (sheet flooring) may contain high concentrations of  asbestos.  The paper packing tears easily and can result in high fiber  levels if disturbed and appropriate procedures are not used.

Floor tiles

Resilient floor tiles in all  sizes may contain asbestos. A common myth is that you can tell by the  size alone if the floor tile is likely to contain asbestos, you cannot.

Drywall taping compound

Drywall taping compound, or  drywall mud, sometimes referred to simply as drywall, often contains  asbestos.  In addition to covering seams, taping compound is also used  to cover holes, screws and nails and will be feathered out over a large  area for a smooth appearance.  As a result, the entire drywall sheet  should be treated as asbestos containing.


Vermiculite is a light-weight,  fire-resistant material.  It has been used in numerous products,  including insulation for attics and walls. If you have vermiculite  insulation in your home, you should assume this material is contaminated  with asbestos, unless appropriate sampling by a qualified person  determines otherwise.

Asbestos cement board and tiles

Cement boards are often located  on exterior buildings, forming wall coverings and roofs. They may appear  as flat sheets, in corrugated sheet or as smaller overlapping tiles.   They may be used indoors in electrical panels, as a heat shield around  fireplaces and heating components, as blackboards, as peg board and as  wall coverings.

Asbestos cement pipes

Asbestos cement pipes are commonly found as water supply and drain pipes.

Textured decorative coating

Textured and decorative finishes on walls and ceilings in older buildings often contains asbestos.



Are you planning to renovate or demolish a  house built before 1990? If so, your house most likely contains asbestos  — a highly dangerous and toxic material. To avoid exposure, you must:

  • Have an asbestos abatement expert to inspect  your home to determine where asbestos-containing materials are before  you begin your renovations
  • Have all identified materials removed by someone trained in asbestos removal. Unsure where to find an expert. Call our BC Green Construction & Demolition team to help you with it.
